- Documentation for L-C/DIR.COM
- (Lower-case directory program)
- ==============================
-
- This program was found on an RCPM system in California in 1983.
- It came to me without any documentation whatsoever, to replace
- other versions of DIR or SD in the public domain.
-
- Its main advantage is purely aesthetic: all filenames appear in
- "lower-case" letters instead of the standard SOLID CAPS of other
- directory programs. I called it L-C/DIR.COM, which is probably
- not its real name. (You might prefer to simply rename it to D.)
-
- Here are some neat features I discovered:
-
- (1) If you have changed disks without entering a control-C to
- reset the drive, L-C/DIR will indicate this with a message at the
- right, saying " -- Disk is Read Only -- "
-
- (2) If you examine the beginning of the program with PATCH, SUPERZAP,
- or some other disk utility, you will see the words:
- SET THESE:
- DIMVIDEO (8 empty bytes follow; patch address 0118-011F)
- REGVIDEO (8 empty bytes follow; patch address 0128-012F)
- Put in the necessary codes to set any alternate video or video
- highlighting you prefer. The only thing that will BE highlighted
- is the "Disk is Read Only" message, when it appears. It is not
- necessary to prefix your code with a byte indicating the code
- length. Thus, if ESC-B-1 turns on alternate video, you can just
- enter 1B 42 31.
-
- (3) Normally, the filename and filespace display for a typical
- Read/Write file looks like this:
- filename.typ 12k
-
- - However, if the file is Read Only, the display will be:
- filename.typ 12r
-
- - If the file attribute has been set to ARC, the display will be:
- filename.typ 12K
-
- - If the file is both Read Only and ARC, the display will be:
- filename.typ 12R
-
- - System files do not display at all in L-C/DIR.
-
- If you discover any other features, send me a postcard.
